Rear Brake Adjustment tool

["TJ Tryon, Jr." <tjt@insightbb.com>]

After looking for a few weeks for one of the square wrenches to adjust the
rear brakes (one that won't break like the moss ones), I tracked one down on
a MAC tool truck.  MAC part number:  RW903

It's a ratchety wrench and has 3/16, 1/4, 5/16 and 3/8.  Cost was $13, and
well worth it to have the correct tool.  As a bonus, since it has 4
different sizes, I can do both the B and the Midget.
